More or less economical to breed your own mice?

[Pareeeee]

So I know I've said in the past that I didn't like the idea of feeding live prey, but after giving Boaz a few live mice I realized it doesn't bother me like I thought it would. Also he really seems to prefer the live prey, and I don't blame him, lol.

Anyway, I was wondering, would it be more economical for me to buy a couple cages and breed the mice myself? Or is that more expensive?

I'm not really sure how difficult it is to breed them since I haven't done my research yet. First I want to know if it's even worth it in the long run, money-wise.

Any ideas?

PS: To buy mice individually at my local pet store it costs me somewhere around $3.50 each.
